I am pleased that the mount holds it set position so well after selecting a new position. After about 5 or 6 range trips, the positions are still "tight". I was dubious at first, thought the mount appeared too "plastic". Now I just think of it is a polymer mount, LOL. It is mounted on a 5.56 rifle.
Pros: Light. Locks up tight in positions
Cons: Each Position needs to be "worked in a bit" before position switching becomes flawless.
